A report by market research firm points to Google’s Android taking second slot behind Symbian (used widely by Nokia). Whilst Symbian currently holds the top OS slot, second place is RIM’s Blackberry followed by the iphone. I have blogged about the potential of Android previously and with the release of the Droid and Nexus One phones, there are some serious handset contenders. When combined with Google’s more open source approach to the OS and app stores will drive them into second place within just three years.
